Hi everyone. Stripping down the engine and don’t want to break this which I think is the breather?. I’ve got the hex nuts off but it’s fixed to the block. Just don’t know how to release it. Thank you
It's just pushed in. Probably the gasket in the bolted part is sticky. If you add momentum there, or tap it with a plastic hammer, it will come loose. You can then rotate/ wiggle the breather out.
